Lesson: Rotational Kinetic Energy Physics

Start Practising

In this lesson, we will learn how to calculate the rotational kinetic energy of a rotating object from its moment of inertia and its angular velocity.

Lesson Plan

Students will be able to

  • use 𝐾=12𝐼𝜔 to calculate the rotational kinetic energy of an object,
  • understand that 𝐾=12𝐼𝜔 is the rotational analogue of 𝐾=12𝑚𝑣.
